An eprint is a digital version of a research document (usually a journal article, but could also be a thesis, conference paper, book chapter, or a book) that is accessible online, whether from a local Institutional, or
a central (subject- or discipline-based) Digital Repository.
When applied to journal articles, the term "eprints" (or "e-prints") covers both preprints (before peer review) and postprints (after peer review).
